Supermassive black holes lurk at the centers of massive galaxies, including our own Milky Way. Puzzlingly, supermassive black ...

Astronomers using the NASA/ESA/CSA James Webb Space Telescope together with the NASA/ESA Hubble Space Telescope have looked deeply at thousands of young star clusters in four nearby galaxies, studying ...

Astronomers using the James Webb Space Telescope have made a surprising discovery about a galaxy long, long ago and far, far ...

The Milky Way may not have a sharp edge, but scientists have now found where its star-forming activity largely comes to an ...

Astronomers have finally identified where the Milky Way’s star-making activity fades, uncovering a long-sought boundary in ...

A massive, dust-packed galaxy seen just 400 million years after the big bang is leaving astronomers scratching their heads.

At approximately 100,000 light years in diameter, the Milky Way’s vastness and the broader, ever-changing dynamics of the cosmos defy any attempt to fully understand our home galaxy and its history.

New findings from a large survey of galaxies suggest that star formation is largely driven by the supply of raw materials, rather than by galactic mergers that trigger sudden bursts of star formation.

Astronomers studying galaxy evolution have long struggled to understand what causes star formation to shut down in massive galaxies. Although many theories have been proposed to explain this process, ...

These three galaxy images from the AEGIS survey show a range of galaxy types: a disk-like spiral galaxy (top), a cloud-like elliptical galaxy (middle), and an irregular galaxy resulting from a ...
